Preacher Curl

The preacher curl anchors your upper arms against a pad, eliminating any chance of swinging. This makes it one of the purest bicep isolation exercises — the short head is fully stretched at the bottom.

Form Guide

Step-by-step: Preacher Curl

1Sit at the preacher bench, upper arms resting on the pad fully.
2Start with arms fully extended — a full stretch is the most important part of this exercise.
3Curl the bar to your chin, contracting the bicep fully.
4Lower with complete control — resist the urge to let gravity win on the way down.

Common Mistakes

What most people get wrong

Not reaching full extension: losing the stretched position removes half the stimulus.
Bouncing at the bottom: control the stretch rather than using the elastic reflex.
